Zent-al shaft 19, whereby on the rotation of the latter, the said trains of gears will be simultaneously actuated for a purpose, asl

will be hereinafter more fully described.

On the outer face of the casing 22 is fixed a dial 29, on which are suitably printed or otherwise marked independent circular charts 30 and 3l, the chart 30 being disposed concentrically with respect to the main arbor 24, While the chart 31 is arranged concentrically With respect tothe auxiliary arbor 26. The chart 30 is suitably marked with a. graduated scale representing different prices for a unit of weight, and also different units of weight. Also, the chart 3l is provided Witlra graduated scale sho-Wing f actions of units of Weight and the price per fraction of the unit of Weight.

Secured to the main arbor is an indicator hand or pointer 32. Also secured to the auxiliary arbor 2G is an indicator hand or pointer 33, these pointers orhands being adapted to sweep or traverse over their respective charts 30 and 3l when the scale is being operated, so that on the Weighing of material, both the unit of weight and the price per unit may be computed.

ln practice, the article Whose value and weight is to be computed is placed upon the platform ll, which instantly causes the rising of the scale beam l5, thereby rot-ating the pendulum carrying shaft l) which causes the actuation of the trains of gears 24 which effects the turning of the indicator hands or pointers 32 and 323, so that the same will sweep over the charts 30 and 3l to predetermined points thereon for indicatingr the aggregate number of pounds or faction thereof, and simultaneously the price per pound and the price for the units at which the article is sold. It is to be understood, otl course, that the charts 30 and ft may be altered by way of changii'ig the graduated scales thereon, so that an increased or decrcasial number of pounds may be computed, and likewise the price per unit or fraction thereof of the uf'eight of the article tov be sold.

lVhat is claimed l. A. scale of the class described, comprising a base, a liost rising therefrom, a frame supported on said post, a scale beam pivotcd of weight' l l l l l l l i i l j in said frame, a platform mounted upon the base and having connection with the scale beam, a .casing fixed to the frame, trains of gearing rotatably. mounted in the casing, a rotatable shaft mounted in the frame and having, connection with the trains of gearing, a toothed sector formed on the free end of the said beam, a gear'fixed to said shaft and interineshing with the said sector, a weighted pendulum fixed t0 said' Shaft, a dial having independent charts provided with graduated scales, .and pointers act-uated by the trains of gears and adapted to traverse the said scales on the dial.

2. A scale of the' class described, comprising a support, a platform carried thereby, a rocking scale beam above said support and having connection with said platform, a rotatable shaft having a gear, a toothed sector carried by the beam and intermeshing with the gear, a weighted pendulum fixed to the said shaft, a casing connected with the support, a train of gearing journaled in said casing and having connection with the said. shaft, a, dial carried by the casing and having a graduated scale thereon, and a pointer connected with the train of gearing and adapted to traverse the said graduated scale.

3. ln a con'iputing scale, a support, a platform carried by said support, an upright rising` from said support, a frame connected with said upright, a rotatable shaft journaled in saidframl and. having a Weighted pendulum, a rocking beam connected with said platform and supported in the frame, a gear fixed to said shaft, a toothed sector lixed to said beam, and intermeshing with the gear, a easing fixed to said frame, a main arbor journaled in said casing, an auxiliary arbor journaled in said casing, independent trains of gearing operated by said shaft and actuating said main and auxiliary arbors, charts carried by the casing and disposed concentrically with respect to the said main and auxiliary arbor-s, and pointers carried by said arbors.

ln testimony whereof I aflix my signature in presence of two witnesses.
